Abstract

A vehicle navigation apparatus determines whether or not the currently traveled route having a current vehicle position matches with estimated routes after determining, on the basis of the traveled route history, the estimated routes which correspond to destination candidates. Then, the navigation apparatus further determines whether or not the subsequent portion of the estimated route overlaps with other estimated route, for selecting one of the destination candidates. The vehicle navigation apparatus thus selects the destination candidate, in a highly accurate manner in terms of user preference, based on the traveled route history.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]The present application is based on and claims the benefit of priority of Japanese Patent Application No. 2008-170439, filed on Jun. 30, 2008, the disclosure of which is incorporated herein by reference.TECHNICAL FIELD[0002]The present disclosure generally relates to a vehicle navigation apparatus having a map-matching function and a history recording function.BACKGROUND ART[0003]The vehicle navigation apparatus, when operated by an occupant of the vehicle through operation interface such as an operation switch, a remote controller or the like, sets a destination in the apparatus, searches for a route to reach the destination, and warns a driver / occupant of the vehicle that a traffic congestion is expected on the searched route together with a display of an alternative route that avoids the traffic congestion. The driver of the vehicle, however, does not always operate the operation interface of the navigation system for setting the destin...
